CATTLE GUARD.

Application filed August? 1925. Serial No. 47,824.

1 '0 all whom it may concern:

Be it known that I, HARLEY R. SELBY, a citizen of the United States, residing at the city and county of Kalamazoo, State of Michigan, have invented certain new and useful Improvements in CattleGuards, of which the following is a specification.

This invention relates to improvements in cattle guards.

The main object of this invention is to provide an improved cattle guard unit which is very economical to produce and which when in position in the road bed is open and free for the circulation of air with a relatively small amount of metal contacting with the ties by which it is supported, and at the time is very strong and durable.

Objects pertaining to details and economies of my invention will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification. The invention -is clearly defined and point-ed out in the claims.

A structure embodying the features of my invention is clearly illustrated in the accompanying drawing forming a part of this application, in which:

Fig. 1 is a fragmentary perspective view showing the manner of mounting my improved cattle guard units upon the ties of a railway track.

Fig. 2 is an enlarged fragmentary per spective View.

Referring to the drawing, my improved cattle guard unit comprises a pair of angle iron body members 1 disposed with their angles facing inwardly and downwardly, the horizontal arms 2 of the members being substantiallyv spaced while the vertical arms 3 thereof are adapted to rest upon the ties 4.- as indicated in Fig. 1. i

The body members are rigidly connected by the tooth bars 5, the connecting means shown being the rivets 6, although theymay be spot welded or otherwise secured. These tooth bars are provided with upstanding teeth 7 which are preferably disposed in the plane of the vertical arms 3 of the body members, the purpose of this being to substantially space the teeth with a minimum amount of metal and also to add to the appearance of height of the teeth, the height of the teeth being that of the teeth plus the width of the vertical arms of the body members.

The teeth are formed by the diagonally cut ends 8 so that the series of teeth of each unit, have a staggered zig-zag relation, thus giving the units a uniform appearance when viewed from either end. This also results in a saving of metal as there is no waste stock resulting from the forming of the teeth, which are preferably cut from strips of metal.

My improved cattle guard units are very economical to produce and at the same time are effective, strong and durable. Further, there is opportunity for free circulation of air to dry the portion of the ties below the guard units.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is:

1. A cattle guard unit consisting of a pair of angle iron body members disposed in opposed spaced relation with their angles facing inwardly and downwardly, and a plurality of tooth bars secured in spaced relation upon the horizontal arms of said body members, the ends of said tooth bars being cut (liagonally opposite and turned upwardly providing a series of teeth with tips arranged in zig-zag relation.

2. A cattle guard unit consisting of a pair of angle iron body members disposed in an opposed inwardly and downwardly facing spaced relation, and a plurality of cross bars having upstanding teeth at the ends thereof mounted upon said body members.

3. A cattle guard unit consisting of a pair of angle iron body members disposed in an opposed inwardly and downwardly facing spaced relation, and a plurality of cross bars having upstanding teeth mounted upon said body members.

In Witness whereof I have hereunto set my hand. 1

HARLEY R. SELBY.
